| Abstract: | A rubidium-selective electrode has been developed by coating a graphite rod with a PVC membrane containing decylidene bis(4′-benzo-15-crown-5) ether, which is used as a neutral carrier. This electrode exhibited a near Nernstian response to rubidium in the range 1.0 × 10−1to 5.0 × 10−5mol/liter with a slope of 52 mV/pC. The detection limit was 2.0 × 10−5mol/liter. This decylidene bis(4′-benzo-15-crown-5) ether is a new compound prepared by Sichuan University and has never been used to prepare a rubidium electrode. |
